Benefits of technology

The present invention relates to an imaging apparatus that can automatically adjust its focus and brightness based on the distance between the camera and the object being photographed. The apparatus includes a processor that determines if the camera is out of space when it is inserted into the space. When this occurs, the processor initiates a power-saving control to reduce the amount of light consumed by the camera. The processor can also determine if the camera has gone into space when it initiates the power-saving control. The power-saving control can be executed by reducing the brightness of the light source and the amount of irradiation light. The apparatus can also adjust the focus based on the brightness of the object being photographed. The technical effect of this invention is to improve the accuracy and efficiency of the imaging apparatus by automatically adjusting its focus and brightness based on the distance between the camera and the object being photographed.

Problems solved by technology

As the battery capacity increases, the weight of a wireless endoscope increases.
For this reason, portability is lost.

first embodiment

Modified Example of First Embodiment

[0072]A modified example of the first embodiment of the present invention will be described. In the modified example of the first embodiment, the controller 101 determines whether or not the imaging device 102 has gone out of the space on the basis of the amount of the irradiation light of the light source 103.

[0073]The controller 101 determines the brightness on the basis of the image data. The controller 101 decides on the amount of the irradiation light of the light source 103 on the basis of the brightness. The controller 101 controls the light source 103 on the basis of the decided amount of the irradiation light.

[0074]The controller 101 determines whether or not the brightness meets a brightness condition in Step S101 shown in FIG. 4. The brightness condition represents that the amount of the irradiation light is continuously greater than a light amount threshold value in a determination period. When the amount of the irradiation light meets...

second embodiment

[0079]FIG. 9 shows a configuration of a transmission terminal 100a according to a second embodiment of the present invention. The same configuration as the configuration shown in FIG. 2 will not be described.

[0080]The transmission terminal 100a includes a lens 108 in addition to the configuration shown in FIG. 2. The lens 108 forms an optical image that is based on light reflected by a subject on the imaging device 102. The focal position of the lens 108 is changeable. The controller 101 executes auto-focus control (AF control).

[0081]The controller 101 adjusts depth of field by adjusting at least one of the focal position and the diaphragm. In this way, the controller 101 changes the imaging condition of the range to which light is emitted by the light source 103 to a condition suitable for imaging.

[0082]The transmission terminal 100a executes the processing shown in FIG. 4 in the normal mode. The same processing as the above-described processing will not be described.

[0083]The cont...

third embodiment

[0092]A third embodiment of the present invention will be described by using the transmission terminal 100 shown in FIG. 2. In the third embodiment, the controller 101 determines whether or not the imaging device 102 has gone out of the space on the basis of the distance from the imaging device 102 to an object in the space.

[0093]The transmission terminal 100 executes the processing shown in FIG. 4 in the normal mode. The same processing as the above-described processing will not be described.

[0094]The object in the space is a tubular wall surface. The controller 101 estimates the distance from the imaging device 102 to the wall surface in Step S101. The controller 101 determines whether or not the distance meets a distance condition (sixth condition) in Step S101. The distance condition represents that the distance is continuously greater than a distance threshold value (fourth threshold value) in a determination period (sixth period). When the distance meets the distance condition...

Abstract

An imaging apparatus includes a processor, an imaging device, and a light source. The processor is configured to determine whether or not the imaging device has gone out of space of which at least part is surrounded by an object when the imaging device is performing imaging after the imaging device is inserted into the space. The processor is configured to execute power-saving control when the processor determines that the imaging device has gone out of the space. In the power-saving control, the processor is configured to make power consumption of a control target less than power consumption of the control target before the power-saving control is executed. The control target is at least one of the imaging device and the light source.

Description

BACKGROUND OF THE INVENTIONField of the Invention[0001]The present invention relates to an imaging apparatus, a method of operating the imaging apparatus, and a recording medium.[0002]The present application is a continuation application based on International Patent Application No. PCT / JP2018 / 016581 filed on Apr. 24, 2018, the content of which is incorporated herein by reference.Description of Related Art[0003]Wireless endoscopes operating with batteries have been developed in recent years. As the battery capacity increases, the weight of a wireless endoscope increases. For this reason, portability is lost. Thus, it is desirable that a wireless endoscope does not waste power.[0004]Japanese Unexamined Patent Application, First Publication No. 2013-094318 discloses technology of updating a correction table for correcting the battery residual capacity. In addition, Japanese Unexamined Patent Application, First Publication No. 2013-094318 suggests updating the correction table when equ...
